At that point, the second one should either have been an edit with more/changed info to the initial note, or it's adding additional info so you would have two files linked that are like {timestamp}_radioactive_mayonnaise {newer_timestamp}_making_radioactive_mayonnaise, etc. There isn't really a reason to have two notes with the same name anyway (in the same way that you couldn't have two files called radioactive_mayonnaise.md in the same directory and wouldn't want that in your search and linking). It's okay to go back and add more info to an existing note, or make a new note with a more descriptive name if warranted.
